Frame spacing and fixings depend on the board thickness and the job. SCG's countersunk screws drive without pre-drilling, and each joint type has its own filler. Framing, screws and sealants are in cement board installation accessories.
Application | Thickness | Framing and spacing | Fixings | Joints |
|---|---|---|---|---|
Ceiling or soffit, timber frame | 3.5–6 mm | 1.5x3 in timber, max 60 cm apart | 1–1.5 in nails | Polyurethane sealant |
Ceiling or soffit, steel frame | 4–6 mm | Galvanized gauge 24 (0.55 mm), main runners 100 cm, battens 40 cm | 23 mm sharp-point screws | Polyurethane sealant |
Interior wall | Square edge 8–12 mm or tapered edge 8 mm | C74 and U76 gauge 24 (0.55 mm), max 60 cm apart | Countersunk screws, no pre-drilling | Smart Board joint plaster |
Exterior wall | Square edge 8–16 mm | C75 structural steel 1.2–3.2 mm, max 60 cm apart | 32 mm winged drill-point screws | Polyurethane sealant |
Floor | Square edge 16–18 mm | Structural steel joists 30–40 cm apart (see the table below) | 45 mm winged drill-point screws every 40 cm, 1.2 cm from the edge | Gumcrete |
Underlay on a concrete floor | Square edge 8–12 mm | Latex adhesive over the whole back | 1 in concrete nails (8 mm) or 1.5 in (10 mm and up) every 40 cm | 1 cm joint gap |
A 16–18 mm Smart Board floor carries 150–500 kg/m², depending on thickness and joist spacing. Use this table for a first pick, and have an engineer size the actual framing.
Thickness | Joist spacing | Building type | Design live load |
|---|---|---|---|
16 mm | 40 cm | Houses and homes | 150 kg/m² |
18 mm | 40 cm | Condos, hotels, dormitories | 200 kg/m² |
18 mm | 40 cm | Offices, banks | 250 kg/m² |
18 mm | 40 cm | Shophouses, universities, schools | 300 kg/m² |
18 mm | 30 cm | Malls, halls, restaurants | 400 kg/m² |
18 mm | 30 cm | Warehouses, factories, print shops | 500 kg/m² |
Keep point loads under 100 kg on any 10 cm² and avoid floors that stay wet. On runs longer than 6 m, leave a movement joint through the boards and the tiles and seal it with polyurethane. Smart Board is non-combustible to BS 476 Parts 5, 6 and 7. The 4, 6, 8 and 10 mm boards bend to radii of 1, 1.5, 2 and 4 m. An 8 mm Smart Board wall clad on both sides reaches STC 38 and weighs about 30 kg/m² with framing, against about 180 kg/m² for rendered brick.
Smart Board is SCG's fiber cement board, made from cement, silica sand and cellulose fiber and cured in a high-pressure autoclave to TIS 1427-2561. The name is so well known that many people use it for any brand of cement board. Smart Board comes in 3.5 to 20 mm for ceilings, walls and floors.
Resists water, sun, termites and fire, inside and out, with a smooth face ready for paint. SCG makes a full installation system, from framing and screws to adhesive and joint compound, so every part is designed to work together.
